A R22 refrigeration system is used to operate between 45degC and -30degC. The total cooling capacity is 350 kW. a. What is the ideal COP of the system? b. What is the heat rejected by the system? c. What is the total power consumed by the system? There are several steps made to improve the performance of the system. What happens to the COP, heat rejected and power consumed by the system when: d. For the same evaporator and condenser pressure, the temperature at the entrance of the compressor is -20degC, and the inlet to the expansion valve is subcooled by 5degC. Due to the wide temperature gap, it is decided to use a two-stage refrigeration system using flash gas removal and optimal intercooling operation in a flash chamber. What happens to the COP, heat rejected and power consumed by the system when: e. Having a low pressure and high-pressure compression. f. Two evaporators and two compressors, with the lower temperature evaporator having a cooling capacity of 225 kW. Notes: The…
In actual design, as per illustration Fig. MT 1, the system has a liquid reservoir also acting as an accumulator. The line that connects to the thermal expansion valve is connected underneath the accumulator. This will ensure that only ___ refrigerant will be atomized by the value supplied to the evaporator.
